SOCKET WRENCH.

Application filed April 18, 1922. Serial No. 554,708.

To all whom it may concern:

Be it known that I, l/VILLIAM H. Fist-inn, a citizen of the UnitedStates, residing at Altoona, in the county ofBlair and State ofPennsylvania, have invented certain new and useful Improvements inWrenches, of which the following is a specification.

This invention relates to an improved wrench and seeks,'as one of itsprincipal objects, to provide a deviceof this character adapted for awide range of use and where in different sets of jaws may bG QIIIPlOyGClin connection with the core of the wrench, thus enhancing theadaptability of the wrench.

A further object of the invention is to provide a device wherein thejaws may be readily adjusted and locked in adjusted position.

The invention has asa still further ohjeet to provide a device whereinthe ad justing means for the jaws will also provide a locking meanstherefor adapted to automatically lock the jaws in adjusted position.

And the invention has as a still further object to provide a devicewhichwill be characterized by structural ruggedness and simplicity tothe end that the wrench may prove entirely eflieient and satisfactory inpractical use Other and incidental objects will appear hereinafter Inthe drawing:

Figure l is a side elevation of the wrench;

Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 3, lookingin the direction of the arrows;

Fig. 3 is a vertical sectional view on the line 3-3 of Fig. 1, lookingin the direction of the arrows; and p i Fig. at is a perspective viewshowing the jaws of the wrench in detail.

In carrying the invention into effect, I employ a cylindrical core orstock 10 provided at its upper end with annpstanding squared boss 11which is hollow so that a wrench or other tool may be inserted into theboss or may be engaged with the boss externally. Formed through thestock is a square diametric opening 12 above which is a transversecylindrical opening 13 lying parallel to the opening 12 and connectingsaid openings is a slot 14. Overlying the Socket vders 18 extending fromthe side faces of the i from the base ends of the guide members lowerend portion of the stock to project therebeneath are companion awswhich, for convenience, have been indicated at 15 and 16 respectively.vThese jaws are provided with angular inner faces for engagement with anut or with the work and projecting laterally from the upper end of thejaw 15 is a squared guide member 17 provided'at its base withlongitudinally directed shoulmember fiushwith the lower side thereof.The aw 16 181 01311661 at its upper end with a mating channel-shapedguide member 19 which is open at its lower side and is adapted toslidably receive the guide memher 17 therein. At its upper side theguide member 19 is provided with a notch 20 while the outer ends of thesides of said guide member are cut away at their lower edges, asindicated at 21, to ride over the shoulders 18 of the guide member 17 Asshown in Fig. 2, the mating guide members 17 and 19 are snugly butslidably received in the opening 12 of the stock 10 so that the walls ofsaid opening will eoact with said guide members for locking the jaws 15and 16 against rotation extending longitndinally of the stock while thesides of the guide member 19 will 'coact with the shoulders 18 of theguide member 17 and said 8 guide members, in turn, coact with the top 8and bottom walls of said opening for sustaining the jaws against cantingspreading movement at their free ends. Upstanding .90 at their uppersides, are triangular shaped tail lugs 22 grooved at opposite sidesthere-- of to project freely through the slot 1 in the stock into theopening 13 therein, it being observed that the lug upon the guide member17 is received in the notch 20 of the guide member 19. Formed on theconfronting faces of said lugs are centering studs 23 and freely fittingin the opening 13 of the stock to bear between the lugs is It?!) aspring 2st engaged at its ends over said studs and tending to separatethe aws. At their outer sides, the lugs 22 are, as most clearly shown inFigure 2-, provided. with inclined faces 25 and threaded upon the 195upper end portion of the stock to coact with said lugs is a nut 26 thelower inner corner of which is cut away to provide a beveled face 27sea-ting fiat against the beveled faces 25 ofthe lugs, a being observedin this unent of the j aws may thus .be readily efi'ected and byproviding several sets of jaws of dififerent sizes and shapes inconnection with .the stock 10, the range of useof the wrench may be.grea-tly augmented. In this connection, it is to be noted that while Ihave described the device as .a. wrench, still the device may also beenployed-asa chuck for use in connection with lathes orthe like, and

,such adaptations of the invention are accordingly contemplated herein.

Having .thus described the invention, what is claimed as new is:

1. .A-.Clevice of the character described including a Stock having anopening there- ;through, coacting aws adjustable upon the stockmandhaving slidably .ma-ting guide members .fitting' in said openingcoacting with .each other, the guide member of one of said jaws beingsquared and provided :with longitudinal shoulders and :the guide member.of the other of said jaws being. channel-shaped to slidably it thefi-rstguide member coacting with said shoulders, and

means upon the stock for adjusting the jaws.

2. A device ofthecharacterdescribed ineluding a stock havinga squaredopening .therethrough and provided in spaced relation to said openingwith a. second opening joined with the first opening by ,a connect ingslot, coacting jaws adjustable upon the stock and provided withmatingguide members fitting in the first opening of the stock, lugsupstanding from said guide members -to project through said slotinto'the second mentioned opening of the stock, a spring bearing betweensaid lugs tending to separate the jaws, the lugs being formed withinclined faces, and a nut adjustable upon the stock to coact with saidinclined faces of the lugs for shifting the j awstowardeach other.

3. Adevice of the character described includnig a stock, companlon awscarrled thereby and provided with mating guide members one slidablyfitting into the other and both 'coacting with the stock connecting thejaws thereto, and means upon the stock for shifting the jaws towardieachother.

:4; Adevice of the class described includng-a stock having an openingtherethrough, companion, aws earned by the stock and provided withmating guide members fitting insaid opening slidably connecting the awswith the stock, one of said guide members being squared and the other ofsaid members being channel-shaped .to embrace said firstnentionedmember, and means upon the stock for djusting the jaws.

5. A device of the class described including a stock, eoacting awsadjustable thereon and provided with mating laterally directed guidemembers :slidably connecting the jaws with the stock, lugs upstandingfrom the jaws, the stock being provided with an opening, a springdisposed in said opening bearing between said lugs tending vto separatethe jaws, and uneans adjustable upon the stock for shifting :the jawstoward each other.

In testimony whereof I afiix my signature.
